A person pushes a crate on a frictionless surface with a force of 100. lbf. The crate
Question:
A person pushes a crate on a frictionless surface with a force of 100. lbf. The crate accelerates at a rate of 3.0 feet per second2. What is the mass of the crate in lbm? (A: 1.07 × 103 lbm)
Assume that on the surface of the Earth, g = 9.81 m/s2 = 32.2 ft/s2 (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
